Abstract: An immersion cooling system includes a cooling tank, a housing and a valve. The coolant tank is configured to accommodate a liquid coolant and an electronic device immersed in the liquid coolant. The housing covers a side of the cooling tank and thereby forms an enclosure. The valve has two ports, one of which communicates with the enclosure and the other communicates with a part of the cooling tank above the liquid coolant. The valve is configured to open in response to a gas pressure inside the cooling tank exceeding an upper limit.

Abstract: The present disclosure provides an immersion cooling system for a server cabinet including a plurality of server boxes, a cooling tank and a plurality of liquid connecting pipes. Each server box includes an electronic device immersed in the cooling liquid, and the electronic device generates a thermal energy so that part of the cooling liquid evaporates into a hot vapor. The cooling tank is connected to the plurality of server boxes and includes a condenser and a storage part. The condenser is connected to each server box and condenses the hot vapor to form the cooling liquid. The storage part storages the cooling liquid from the condenser. Two ends of the liquid connecting pipe is connected to the storage part and the server box respectively. The cooling liquid in the storage part and the cooling liquid of each server box are maintained in a same liquid level.

Abstract: An immersion cooling system includes a cooling tank and a filtration system. The cooling tank is configured to accommodate a liquid coolant and an electronic device immersed in the liquid coolant. The filtration system includes a pipeline, a pump, a filter and a cooling device. The pipeline is in fluid communication with the cooling tank. The pump is disposed in the pipeline and is configured to drive the liquid coolant to flow through the pipeline. The filter is disposed in the pipeline and is configured to filter the liquid coolant. The cooling device is connected to the pipeline and is configured to cool the liquid coolant. The pipeline has an inlet connected to the cooling tank. The cooling device is located between the pump and the inlet of the pipeline.

Abstract: An immersion cooling system includes a tank, a first condenser, an enclosure, a second condenser and a connecting pipe. The tank has a first space. The first space is configured to accommodate a cooling liquid for at least one electronic equipment to immerse therein. The first condenser is disposed inside the tank. The enclosure is disposed outside the tank. The enclosure forms a second space together with the tank. The second condenser is disposed in the second space. The connecting pipe includes a first end and a second end opposite to the first end. The first end is connected with the second condenser. The second end is communicated with the first space.

Abstract: An immersion cooling system includes a tank, an isolation plate and a condenser. The tank includes a base plate and a sidewall connected with the base plate. The sidewall defines with the base plate a space configured to accommodate a cooling liquid. The isolation plate connects with the sidewall or the base plate and divides the space into a first subsidiary space and a second subsidiary space. The first subsidiary space is configured to accommodate electronic equipment which is immersed in the cooling liquid. The isolation plate and the base plate are separated from each other. The sidewall surrounds the condenser. A vertical projection of the condenser towards the base plate at least partially overlaps with the second subsidiary space. The electronic equipment evaporates a portion of the cooling liquid to form a vapor. The condenser is configured to condense the vapor into a liquid form.
